Dan Hooper - Fermilab/University of Chicago Community Summer Study (Snomass 2013) On behalf of the CF4 Working Group (Manoj Kaplinghat, Konstantin Matchev, DH) The Dark Matter Discovery Age In a sense, we have already discovered dark matter Observations of galaxy dynamics, galaxy clusters, large scale structure, the cosmic microwave background, light element abundances, etc. collectively provide an overwhelming body of evidence in favor of the conclusion that most of the matter in our Universe consists of (relatively) cold and collisionless particles Despite considerable effort, no viable alternatives to this conclusion have been proposed But we have not yet identified the nature of the particle(s) that make up the dark matter No particles contained in the standard model are viable dark matter candidates – dark matter is new physics The Dark Matter Discovery Age In a sense, we have already discovered dark matter Observations of galaxy dynamics, galaxy clusters, large scale structure, the cosmic microwave background, light element abundances, etc. collectively provide an overwhelming body of evidence in favor of the conclusion that most of the matter in our Universe consists of (relatively) cold and collisionless particles Despite considerable effort, no viable alternatives to this conclusion have been proposed But we have not yet identified the nature of the particle(s) that make up the dark matter No particles contained in the standard model are viable dark matter candidates – dark matter is new physics After decades of experimental progress, we are currently in a position in which many or most of the best motivated dark matter candidates are within reach of near future experiments – The successful detection of dark matter particles within the next decade seems likely SLAC 5/25/13 18:39 Cryogenic Solid State CDMS/SuperCDMS EDELWEISS/CRESST/EURECA CoGeNT/C4 TEXONO/CDEX Liquid Xenon LUX/LZ XENON PandaX XMASS Liquid Argon ArDM Darkside DEAP CLEAN Crystal and Annual Modulation DAMA/LIBRA KIMS ELEGANT ANAIS SLAC 5/25/13 18:39 CINDMS Princeton NaI WIMP Direct Detection CensusDM-Ice Cryogenic Solid State CDMS/SuperCDMS Threshold Detectors EDELWEISS/CRESST/EURECA Technology Description 1.
